Research Interests:
My research interest focuses on use of modern tools in Molecular Biology to overcome biotic and abiotic constrains of food production as well as enhancing the understanding of modern biotechnology.  Specifically, my research revolves around five interrelated areas; i) long distance RNA trafficking between parasitic plants and their hosts, ii) RNA interference (RNAi) as a resistance mechanism against parasites – Striga and Cuscuta, iii) genetic engineering strategies for enhancing drought tolerance in tropical crops, iv) Agrobacterium rhizogenes transformation of cereals as a functional genomics tool for plant-parasite interactions, and v) molecular mechanisms of parasitic plants/host plants interactions.
